ALFRED L. SOHM, OF CHICAGO, ILLINOIS, ASSIGN'OR TO SOHM'. ELECTRIC 'SIGNAL & RECORDING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ARIZONA.

ELECTRICAL RECORDING APPARATUS.

Specification'of Letters Patent.

Application filed Octoberi, 1912. Serial No. 724,024;

To all whom it may concern I Be it known that I, ALFRED L. SOHM, a citi zen of the United States, residing at Chicago,'in the county of Cook and State of Illinois, have invented a certain new and useful matic recording and contemplates an improved system and apparatus for making a record of periods of elapsed time.

More specifically, my present invention has to do with an electrically operated printing machine wherein certain selections, in

the way of identifying numbers or letters,

may be made.

It will appear to those sliilled in the art that there may be other uses'for my inven- 'tion, but I contemplate its use particularly in keeping a record of an employees time in sults are printed on a strip of paper and itv will be seen that it is necessary to distinguish one workman from another and I do this by means of a shiftingtype bar which, automatically, is brought into proper position by the manipulation of theproper ke in order that the corresponding workman s.

number or letter may be registered with the other data printed at the same time. This shifting type bar is controlled by a number of electromagnets, two for moving the bar in both directions and two for determining the limits of certain movements of the bar.

. In this way, certain combinations are produced 1n the electrical circuit arrangement in order that the bar maybe made to occupy any one of a number of definite positions. I embody the peculiar arrangement which I have just described broadly in a printing machine whichi involves other printing wheels, ribbon mechanism, and paper advancrng mechanism, and Lregard the entire combination as one of rare 'utilitv in the peculiar results which the association produces. I have,therefo're, drawn claims, not only to the abstract type bar mechanism, but also to the mechanism in combination with the other parts.

luv invention will be clearly understood by referring to the accompanying. drawings, in which r Figure 1 is anelevational view embodying the structural features of my invention; Fig. 2 is a cross-sectional view taken on lines 22 of Fig. 1; Fig. 3 is a top view of the structure shown in Fig. 1; Fig. 4 is a view taken 0.: lines 4-4 of Fig. 1 showing the mechanism from the top after the printing mechanism has been removed; Fig. 5 is a sectional view taken on lines 55 of Fig. 3 showing the disk which engages the paper upon which the printing is done; Fig. 6 is a side view of the mechanism shown in Fig. 5; Fig. 7 is a top view of the electromagnets and the shifting type bar; Fig. 8 is a view similar to Fig. 7 except that the shifting bar is shown in another position; Fig. 9 is an elevational view of the mechanism shown in Figs. 7 and 8 showing the controlling magnets with the shifting bar.

10; and Fig 12 is a diagram illustrating the Y circuit arrangement employed in conjunction with the apparatus illustrated in the.

foregoing figures. Fig. 13 is a view of a part of the record strip, with a record printed thereon. N

At the outset I shall refer to the structural embodiment of my invention. I have shown a foundation plate 13 which is suitably mounted in a supporting base 14. This plate-1 3 has extending upwardly therefrom a plurality of posts 15'which support a top plate 16. At one end of this plate, as shown in Figs. 1 and 3, there is mounted a pair of brackets 17 17 which are connected by means of a yoke 18 which, in turn, supports two electromagnets 19, '19, having their cores -nets 19 and'serves to fasten together the yokes 18 and 20. Each of the brackets 17 p has a pivot .22 which support the arms 23, 23, these arms having attached thereto'an' armature 24 which is adapted to be attracted by the cores of the electromagnets 19, 19. The arms 23 are connected by a connecting rod 25 and have pivoted-thereto at 26 two dogs 27 which are weighted at 28. These dogs are adapted to engage with ratchets 29 'mounted on a pivot rod 30, which is supported in plates 31, 31 extending upwardly from the top plate 16.' ,The pivot rod 30is enlarged between the plates 31 as shown and supports two disks 32, 32 which have prongs or points 33, 33 along the periphery thereof. These points are adapted to engage the paper 34 which, as shown. in Fig. 5, passes between the disk 32 and two smaller disks. 35, these points; being arranged so that. they pass through the paper and engage the smaller disks 35 asshown. This arrangement proyidesa proper advancement of the paper either ofthe ratchets with which it may be placed into engagement '7 as desired and to this end it is provided with an engaging portion 62 extending at .right angles with the body of thepawl 60. The arrangement is such that after the member '53 has been thrown into either one of its positions, itwillhave a tendency to ke'epthe pawl 60 in engagement with veither one ofthe ratchets by means ofthe engagement of the limbs 63, 63 with the" pin 61'. In v.otherwords, the arrangement provides that the frame'39 may be moved downward when the electromagnets 19, 19 are energized, and during this movement, the retaining pawl 60 is maint'ained in engagement with the ratchet 51,

fastened to the frame 39 and extending upon the deenergization of the electromagnets. These disks 35, 35 are mounted upon 7 a shaft 36 journaled in the extensions 37 extending from the side plates 31.' This is shown particularly in Fig. 5. The arms are'provided at one extreme end with pivot pins 38 which engage with a reciprocating member '39 (sufficient play between the parts being provided) which is widened at 40 as shown in Fig. 2 and which has secured in a groove 41 a platen 42, the purpose of which will be described later. The member 39 has at its upper portion an elongated slot 43 through which a constricted portion of the stud 44 passes. This stud extends from a plate 45'at the front of the machine which is secured to thetop plate 16 by means of shown,are held in place by means of screws 49-and 50. These screws are threaded into the front plate 45 and extend backward so as to be engaged bythumb nuts 71, 71.

screws 46. This plate 45 is provided at each side with spools 47 and 48 which are mounted upon pivot rods or screws 49 and 50, respectively, which, in turn, are fastened in the front plate 45. Each of these-spools has attached thereto a ratchet, 51 or '52, which is adapted to'be engaged by a pawl member 53 which is pivoted at 54 to the member 39. The member 53 is pointed at the lower end and engages a spring '55 which is mounted upon the member 39 and is provided with 100 ed ends 56, 56 which engage around pins 57 57 The upper portion of the member 53 is bifurcated as shown and has at each'side thereof prongs or points 58 which are adapted to engage with the ratchets 51 or 52 as may be desired. Pivoted upon the stud 44 and held thereon by means of a screw 59 is a lever 60 which has secured thereto a pin 61 which engages with the bifurcated end of the member 53 as shown. This lever 60 is in the nature of a retaining. pawl for above the slot 74 in the plate 16. Suitable slots 75 are provided in the side plates-31, 31 through which the ribbon passes. When the ribbon has unwound from one spool the member 53a'nd-pawl 60 may be manually thrown into engagement with the ratchet of this empty spool, thusreversing the direction of travel of the ribbon. Proceeding now to a description of the mechanism for disposing the number of an employee in the pathof the platen as it comes down, there ,is suitable 'mechanism'in the form of a bar 76 which is provided with numerals 77 which are in the form of type, that is to say, they are raised from the surface of thebar so that the printing can be.

properly done. As shown in this instance,

ployed about the premises of the establishment during the evening or during the night time. The bar 76 is adapted to be reciprocated and to this end it, is provided with teeth 78, which are engaged by a toothedmember 79 pivoted at 80 and provided at its lower end with a tapered armature 81 dis-f posed in proximity to the cores of theelectromagnets 82 and 83 which are suitably secured below the plate 13. (See Figs. 1'

and 10). The bar 76 is provided with bosses or lugs of which there are three in this in stance, one large central boss 84 and a smaller boss 85 at the right thereof, and a boss 86 at the left of the boss 84. The bosses 84 and 85 are adapted to be engaged by the arma ture 87 pivoted at 88 to a post 89, which has secured thereto a spring .90 which engages v with one end of the armature 87 in order to maintain it in the up position. This particular arrangement is shown in Fig. 9, where the spring 90 engages an extension 91 on the armature and thereby keeps this extension in engagement with the post and consequently maintains the armature up above the path of the bosses 84 and'85 during the reciprocation of the bar 76. The armature 92 is arrangedv to be engaged by the bosses 84 and 86, as the case may be, when the electromagnet 93 is energized. This armature is mounted in the same manner as described in connection with the armature 87 and further description is deemed unnecessary. The armature 87 is brought into its down or attracted position by means of the electromagnet 94. Each magnet has two coils. The bar 76 is provided at each end with grooves 95 and 96 which are arranged to be engaged by pins 97 and 98secured in the supporting posts 99 and 100 at each end of the rod 76. This arrangement is shown in Figs. 1, 4 and 9 particularly.

The circuit arrangement .for controlling the electromagnets will be described later and we shall now describethe' means by a which the difierent numbers are. placed into line with the platen 42 so that the printing of the proper number will be shown. Take for example, where'an employee whose number is 6 enters the establishment. The circuit connectionsare such that the electro-' .magnet 83 is energized and the armature 81 is pulled toward the left. This causes the member 7 9 to advance the rod 76 toward the right until the pin 101 strikes the supporting post 99, as shown in Fig. 7. If p Number '1 had entered the establishment, then the pin' 102 extending downwardly from the rod 76 would have engaged the supporting post 100 and thus limited the movement toward the left of the rod 76,

whereby the numeral 1 would be brought into printing line with the platen 42, the magnet 82 being energized in this case. In order to maintain the bar 76 in its normal position as shown in Fig. 4, I have arranged a bracket 103 as shown in Fig. 10, which bracket has mounted thereon two springs 104 which project downwardly through aslot in the plate 1'3and engage on each'side of'the pin 105 extending sidewise from'the armature 81. These springs co-act so as to return the armature 81" to its normal position after either one. of the electromagnets 82 or83 has been energized. As shown in lishfment and to this end there is pivoted to the post 99 a lever 107 which is bifurcated at both' ends. This lever engages at its end with anextension108 from a reciproeating member 109 which isjgrovided with the indications In and. ut in relief letters. The lever 107 engages at its lower end with a member 110 which is pivoted at 111 and which has secured thereto an armature 112 which is-'adapted to be attracted by either one of the electromagnets 113' and 114 which are suitablysecured to the plate 18f ,As shown in the drawings, the word Out is in line with the platen 'and when the platenis brought downward, this word will be printed upon the paper. In order to maintain the'armature 112 in either one'of its positions there is" arranged a spring115 which engages the lever 107 so as to cause a movement to either one of the. extreme positions. In other words, anintermediate po sition is notdesired since in this position no indication woul'dappear as to whether the loo employee was passing out or into the establishment. This spring, it will be stated, is pointed at its center, like the spring 55, so as ,to throw the lever 107 into either one of its extreme positions, as determined by the energization of either one of the electro-. magnets 113 or 114.

Referring now to' the mechanism which indicates the month, the day of the month, and the hour andthe minute of the day, and

also the year, there is disposed a rod- 116 supported in the post 99 and in one of the osts 15. This rod supports a type wheel 117 indicating a plurality of years and a type wheel 118 indicating the months. The type wheels 119 indicate the day of the month and the typeflwheels 120 indicate, the hour of the day or night. These type wheels 117 are provided with ratchets 121, all of which, exceptthe one associated with the year wheel, are adapted to be engaged by suitable advancing pawls 122, which are secured upon the yoke123 that is mounted upon the rod 116. A plurality of pawls 124 are mounted upon a rod 125 and are employed; to engage the ratchets to prevent back rotation of the type wheels. These pawls are kept in engagement with the ratchets by means of springs'126 which are secured to a rod '127 extending between two side members 128, 128. This particular mechanism constituting the type wheel movement forms no part of my present invention and it is deemed suflicient to refer to it broadly and it is deemed suflicient to state that the minute type wheels are advanced by the advancing pawlsevery minute in accordance with the energization of two electromagnets 129 and 130 which support a yoke 131 to which ispivoted an armatu're 132 which has pivoted thereto at 133 a downwardly extending member 134 which is screw-threaded at its lower end and projects through an opening in the plate 13.

The threaded portion is engaged by a thumb nut 135 which may be securely mounted by means of a screw.

The member 134 has apin 136 extending therefrom which engages in an elongated slot 137 in a rod 138 which is pivoted of a screw. A spring 147 is fastened to the "plate 13 as shown in Fig. 1 and engages with the rod 138 in order to maintain the armature' 132 in its up positioniand to maintain the yoke 123 in its down position. In other words, the mechanism is main tained in the position as shown in the drawings by means of this spring. The thumb nut 146 limits the movement in one direction and the thumb nut 135 limits the movement in the opposite direction when the armature 132 is attracted.

Referring again to the reciprocating. bar 76 and particularly to Figs. 4 and 10 and 11, which show a part 148- which may be integral. with the reciprocating bar 76 and which hasat its central portion thereof a cam recess 149 in which a pin 150 f-egnga'ges during the normal position of the'recipro- .cating bar 76. This pin isattached to a spring 151 which. is adapted to makecontact with a companion spring 152 when the shifting bar is reciprocated by means of the electromagnets' 82 and 83. These springs. are suitably supported by, means of the bracket 153 which is suitably fastenedjto the" plate 13. These springs, as showhi, are insulated from each other so as to maintain an open circuit when the pin is engaging in the recess as shown in Fig. 11.

' Referring now to the circuitfarrangement which is used in conjunction with my invention and which is shown particularly in Fig. 12, I show a battery 154 which is connected by means of a conductor. 155 through the windingof the. electromagnet 82 and by means of the conductor 156 to a key 157 which forms one of a number of keys disposed at the entrance of the establishment. This key is adapted to make connection with the contact 158 which is connected to a conductor159 that leads back tothe negative side of the battery. I

The electromagnets 129 and 130 are connected in series with the ,battery 154 and are connected up to a pair of springs 160 and. 161 which are adapted to contact when the eccentric 162 on the clock 163 is rotated. The

spring 160 is connected by means of a conductor to the other side of the battery. The arrangement is such that the circuit is closed through the electromagnets 129 and 130' once every minute and thus the .type wheels shown in Fig. 4 are advanced at one-minute intervals.

We will now consider aworkman Number 1 as entering the establishment in the morning. He will actuate the In key 164 so that connection is made with the contact 165, so that the armature- 112 is rotated about the pivot 111 by means of the electromagnet 113. This throws 'the member 109 into position so that the word In is directly below the platen 42. The workman will then press the'key 157 so that the circuit is closed from thebattery 154 through the conductor 155 and through the electromagnet 82, and throu h the conductor 156, through the spring 15 and contact 158 and conductor 159, back to the negative side of the battery. The energiz'ation of the electromagnet 82 draws the armature 81 to the right and since the member 79 is rotated, the

shifting bar 76 is forced toward the left.

This shifting bar will cause the springs 151 and 152 to make contact inasmuch as the, pin 150 is forced downwardly and out of the recess 149. A circuit is then closed from the. battery through the conductor 155, through the conductor 166, through the windings of the electromagnets 19 and through the conductor 167, through the springs 151 and 152 through the conductor 167 and through the conductor 159 leading to the negative side of the battery 154. The energization of the 'electromagnets 19 attracts the armature 24 as shown in Fig. 1, when the platen 42 is brought downward and carries the paper 34 with it against the type wheels and the numeral f 1 "which is in line with the platen and the word In which is also in line with the platen. The ribbon 72'is also carried down by means of the platen against the type which is in line with it. Thus, the notation 1s madeupon the paper and a per-- manent record thereby secured. Since the key 157 is closed against the contact 158 just for an instant, the platen 42 will be brought into its up position by means of the spring 64 after the circuit has been opened.

We will now consider the circuit arrangement for workman-number 5, who hasassigned to lllIIl the key numbered 5 as shown in the circuit drawing. As this workman enters the establishment, he also actuates the."

In key so that the Word In is thrown into position, that is to say, in line with the platen 42, after which he depresses his key 168, thus closing a circuit from the positive 7 side of the battery'through-the conductor winding of the electromagnet 93, and from there by means of a conductor 172, through the key 168, and through the contact 173 and from there back to the negative side of the 6 battery. This will serve to draw the armature 81 toward the left and consequently the shifting bar 76 will be-forced toward the right and the boss 86 on this bar will be brought against the armature 92 associated with theelectromagnet 93, this armature having been brought down upon the energization of the magnet, and thus the numeral 5 will be brought into line with the platen. After this shifting movement of the shifting bar 7 6and after'the numeral 5 has been .brought into printing line, the circuit will be closed through the printing magnets 19.

The current will take the following course! From the positive side of the battery through the conductors-155 and 166, through the windings of the electromagnets 19,

through the conductor 167, through the ,springs 151, 152 through conductors 167 and 159, and back to the negative side of the battery. WVhen the circuit is closed through springs 151, 152, the platen is brought down so as to print the workmans number on the paper'and the time at which he enters the establishment. The paper has been advanced since the firstworkman entered by means of the pawls 27 engaging the teeth of the ratchets 29 belpw the position as shown in the drawings, owing to the energization of the electromagnets 19, and when the arms 23 vare forced vupward by means of the spring 64, the ratchets and the disks 32 are rotated, thus advancing the paper a certain distance. I p v v We w1ll now consider a workman as leaving the establishment at a certain hour. It

- is to be remembered, of course, that the clock mechanism is rotating constantly and advancing the type wheels 120 and 121 so as to correspond with the time of the day. We

will consider that a workman whose number is 6 is leaving the establishment. He'will then actuate thekey 17 5 so that connection is made with the spring 174. Current will then flow from the positive side of the battery through the conductor 155, through the winding of the electromagnet 114, through the contact 175, the spring 174, and through the conductor 159, back to the negative side of the battery. This will actuate the arma' ture into a position as 'shownin the drawing and consequently throw the lever 107 into a position so that the member 109 is forced toward the left, thus bringing the word Out into line with the platen" 42. The

Workman will then depress the key 17 6 which makes connection with the contact- 159 back to the negative side of the battery. 1

- he shifting bar 7.6 will be forced toward the right until the pin lOl strikes the post 99, when the numeral 6 is brought into the printing line, after which the circuit is closed through the printing electromagnets 19, through the followingpath from the positive side of the battery, through the conductors 155, 166, through the windings of the electromagnets 19, through the conductor 167 and springs 151 and, 152, conductors 167 and 159, back to the negative side of the battery. The energization of the electromagnets causes the platen to force the paper 34 and the ribbon 72 against the type which are in line withthe platen. Thus a notation is made of the number of the workman as Well as the month, day, and the time of day, and the year, on which he left the establishment. I

Since this particular mechanism is designed td be employed as a'check upon the watchman employed a key\'is assigned to the watchman, whit: he must actuate at different periods of the night during which he is at work. The key for the watchman is lettered W and as he actuates this key,

the following circuit is closed: From the positive side of the battery, through conductors 155 and 166, through electromagnets '19, through conductors 167 and 17 9, through ter W is in line with the platen 42 when the shifting bar is in its normal position, I

as shown in Figs. 1 and 4. Iniordento secure the particular time during which he actuates the key assigned to him, the only operation performed by the machine is when the electromagnets 19 are energized so as to force the platen down against the line of type that happens to be in its path.

Each of the keys which are assigned to the workmen may be of such a nature that they may be associated with a suitable locking mechanism, or these keys may be of. any

other suitable arrangements which may suggest themselves'to those skilled in the art. In the drawing, the workmens keys, as well .as the In and Out keys, are shown as being disposed at the entrance end of the establishment which may be designated by the dotted lines 181, all of the other mechanism being disposed. at a point which is accessible to those who are to retain themeords of the diiferent working periods of vthe workmen.

lit will be seen that each of the electro-' magnets 93 and 94: has a winding for active association with the electromagnet 82, another dlstinct winding for active associatlon with the electromagnet 83. In other words,

the arrangement which I propose, provides means for energizing the electromagnet 82, alone, the electromagnet 83, alone, the electromagnets 82 and 93, the electromagnets 82 and 94, the electromagnet's 83 and 93, or the electromagnets 83 and 94:, Each of these combinations determines a specific position of the type bar, each of these positions pressed, the electromagnet 82 is energized alone and the type bar is moved way overto the left to bring the numeral 1 into the printing line.

When the keyNo. 2 is depressed, the electromagnets 94; and 82 are energized. In

this condition the armature87- is brought down to be engaged by the lug 85 and the bar is stopped in position with the numeral 2 in the printing line.

' magnets 93 and 82 are energized and the armature 92'is brought down to be engaged by the lug 84an d the bar is stopped with the numeral 3 in the printing line. When key No. 4: is depressed, electromagnets 94 and 83' are energized. This brings down the armature 87 to be engaged by the lug 84 and the bar is stopped with the numeral 4 in the printing line.

When key No. 5 is depressed, electromagnets 93 and 83 are energized and armature 92 is brought down to be engaged by lug 86and the bar-is stopped withthe" numeral 5, in theprinting line.

'When key No. 6 is depressed, electromag- When key No. 3 is depressed,.the electronet 83 is energized alone and the bar is brought over to the limit of its movement with the numeral 6 in the printing line.

' The circuit of the printing magnets 19 is normally open, and, as has been described, is automatically closed upon any movement of the type bar. As has been pointed out, the normal indication may be had by merely energizing the printing magnets and the watchmans 'key, therefore, is merely a switch in shunt of the automatically operated springs 151,152. 7 A
